摘要： A security data processing device comprising a processor and memory, the processor configured to: receive a digital document comprising a primary programming requirement for programming a programmable device; determine if there is a record stored in the memory that corresponds to the digital document; receive a programming request from a programming module of a programming machine in communication with said processor, said programming request requesting the programming of the programmable device; determine if the programming request complies with the primary programming requirement in the digital document; and wherein if said programming request complies with the primary programming requirement in the digital document and if there is no record stored in the memory that corresponds to the digital document, the processor is configured to: output programming information to the programming module for programming the programmable device; and permanently store a further record, corresponding to said digital document, in the memory.

摘要： A security profile for programming target devices may be provided. A base security profile may be obtained that defines security parameter(s) having a configurable value. A first security profile, generated from the base security profile, may include security parameter(s) that are assigned with a value of a first set of values by: (i) retrieving the value of the first set of values from a first data storage location coupled to a computing device and setting the configurable value of the security parameter using the retrieved value, or (ii) associating the security parameter with an instruction to obtain the value of the first set of values and set the configurable value of the security parameter using the obtained value, the instruction selected from one or more instructions. A second security profile may be generated from the base security profile in response to receiving further input from for the security parameter(s).

摘要： A method of enabling program code stored on target data processing devices, the method comprising: receiving an in encrypted value of a permitted number of target data processing devices that are permitted to have program code stored on them enabled, and using a security data processing device to decrypt the encrypted value and store the decrypted value on the security data processing device; and for each target data processing device, using the security data processing device to: determine whether the value of the permitted number of target data processing devices is greater than zero; if so, obtain a device identifier from the target data processing device; generate a license key from the device identifier; store the license key on the target data processing device; and decrement the value of the permitted number of target data processing devices.

摘要： A data processing device with a processor, a memory and an access control mechanism, the device having secure and non-secure modes, the memory having secure and non-secure regions, the secure region containing cryptographic data, and the access control mechanism preventing the processor from reading the cryptographic data when the device is operating in the non-secure mode. Also, methods of manufacturing and authenticating such a device, manufacturing an item of electronic equipment that includes such a device, a computer program for storing data on such a device, secure data processing hardware including such a computer program and a method of updating data stored in an item of electronic equipment including such a data processing device.

摘要： A security data processing device comprising a processor and memory, the processor configured to: receive a script comprising at least one instruction set for provisioning a type of programmable device, the instruction set(s) defining one or more cryptographic operations, each of the cryptographic operations referring to a parameter; store the script in memory; verify a signature associated with the script using an authorization key retrieved from memory; receive a programming request from a programming module of a programming machine in communication with said processor, said programming request requesting the programming of a programmable device and identifying an instruction set of the instruction set(s) in said script; for each cryptographic operation in the identified instruction set, determine a value for the parameter and perform the cryptographic operation using the value; and in response to performing each cryptographic operation, output programming information to the programming module for programming the programmable device.
